IndiGo Shares Surge 11% as Crude Oil Slumps After US-Iran Ceasefire​

IndiGo share price surged sharply on April 8, emerging as the top gainer in the Nifty 50 index, as a steep decline in crude oil prices lifted sentiment across aviation stocks. The rally follows a two week ceasefire announcement between the United States and Iran, which has cooled global oil markets.

Shares of InterGlobe Aviation, the parent company of IndiGo, climbed 11.13% to ₹4,744 on the NSE during morning trade. The sharp rebound helped the stock erase all losses incurred since the start of the US-Iran conflict on February 28, during which it had declined 11.5%.

Crude Oil Crash Triggers Airline Stock Rally​

The primary driver behind IndiGo’s rally is the sharp correction in crude oil prices. Following the ceasefire announcement, global crude prices dropped below $100 per barrel, offering immediate cost relief to airlines.

Earlier, the conflict had pushed jet fuel prices significantly higher. According to International Air Transport Association data, the global average jet fuel price surged to $195.19 per barrel for the week ending March 27, nearly doubling from $99.40 at the end of February.

Fuel costs account for approximately 40% to 50% of an airline’s total operating expenses. As a result, any sustained drop in crude oil prices directly improves profitability, making airline stocks highly sensitive to such developments.

Operational and Cost Relief Adds Momentum​

Beyond fuel cost benefits, the ceasefire is expected to ease operational disruptions caused by airspace restrictions during the conflict. Indian carriers have cancelled over 10,000 flights since the onset of the West Asia tensions, impacting capacity and revenues.

Adding to the positive sentiment, the Airport Economic Regulatory Authority has announced a 25% reduction in landing and parking charges across major airports. The relief applies to domestic flights for a period of three months and is effective immediately.

IndiGo had earlier introduced higher fuel surcharges to offset rising aviation turbine fuel costs, a move that may now see moderation if fuel prices remain stable.

Supply Constraints May Persist​

Despite the cooling in crude prices, challenges remain on the supply side. According to Willie Walsh, Director General of the International Air Transport Association, even if the Strait of Hormuz reopens fully, jet fuel supply recovery could take months due to disruptions in Middle East refining capacity.

IndiGo Stock Outlook: What Harshal Dasani Says​

IndiGo shares have risen 18% so far in April, although the stock remains down 8% for 2026. This comes after a strong three year rally between 2023 and 2025, during which the stock gained 113%.

The recent ceasefire has improved the near term outlook, particularly as fuel cost pressures begin to ease. However, the sharp rally also suggests that a portion of the optimism may already be reflected in current valuations.

Harshal Dasani, Business Head at INVasset PMS, said that for an airline, lower aviation fuel costs can quickly change the earnings picture, which explains the sharp reaction in the stock. He added that while the broader structural story remains intact, the next phase of upside will depend on sustained benign fuel prices and consistent operational performance.

Going forward, market focus is expected to shift toward key operational metrics such as passenger demand, yield stability, and execution as IndiGo continues to expand capacity. The company’s strong domestic position, supported by scale, network reach, and cost efficiency, continues to underpin its long term growth story.
